LMS - Macro Programming for Production Line Testing of Loudspeakers

Macro Programming

For production testing applications the LMS software can be controlled by user written Macro programs.

The LMS Macro programming language allows for messages to be written to the screen to prompt operators, control test sweeps, run utilities, control printing of graphs, export data, and conduct Pass/Fail tests.

A custom macro editor is also provided as shown here which features syntax highlighting and color printing.

The analyzer parameters can be saved to disk as QuickSet files, and recalled later to immediately reset all of the control panel parameters.

The LMS system will also generate a TTL pulse which can be used to control external switching of test fixtures, or direct polar plot sweeps using stepper motor driven turntables.

When the macro program is running, the dialog as shown here is active. Messages, prompts, and other data can be displayed for the operator. Menus can also be created.

The dialog provides PASS/FAIL indicators which can be utilitized by the macro script programs.
